■Automatic cruise control cancellation
Cruise control is automatically cancelled
in any of the following situations.
• Actual vehicle speed is more than 10 mph
(16 km/h) below the preset vehicle
speed.
• Vehicle speed is less than 25 mph (40 km/h).
• The slip indicator light blinks and a warning tone sounds.
■If the cruise control indicator light flashes
Turn the ON-OFF switch off once, and then reactivate the system. There may be a
malfunction in the cruise control system if the indicator light does not come on,
flashes again or goes out after it comes on. Have the vehicle inspected by your
Lexus dealer.
CAUTION
■To avoid inadvertent cruise control activation
Keep the ON-OFF switch off when not in use.
■Locations unsuitable for cruise control
●Do not use cruise control in any of the following situations.
Doing so may result in control of the v
ehicle being lost and may cause an acci -
dent.
• In heavy traffic.
• On roads with sharp bends.
• On slippery roads, such as th o
se covered with ice or snow.
• On steep hills.
• On winding roads.

Dynamic radar/ laser cruise control
The vehicle-to-vehicle distance control mode allows the vehicle to follow
another vehicle, adjusting to the leading vehicle’s speed variations, and the
conventional cruise control mode allows for driving at a preset speed, both
without the need to press the accelerator pedal.
■ Selecting a cruise control mode
Selecting the vehicle-to-vehicle
distance contr
ol mode
Turn the ON-OFF switch ON
Push the main switch again to turn
off the system.
Selecting the conventional cruise
control mode Turn the ON-OFF switch ON
Push and hold the lever for more
than one second.
Change to the conventional
cruise mode
The system is set to the vehicle-to-
vehicle distance control mode
each time the ignition is turned
ON.

■Setting vehicle speed
Settings can be made when the vehicle
is traveling above 28 mph (45 km/h).
■Unsuitable conditions
You cannot set the speed in the following conditions:
• When the selector lever is in a position other than D, 4, 5, or 6.
• When driving in adverse weather conditions.
■Automatic cruise control cancellation
In the following cases, the preset speed is can ce
lled. If the system is restored, cruise
control enters the ready mode.
• The slip indicator light blinks and a warning tone sounds.
• The anti-lock braking system activates.
• Foreign matter adheres to the sensor.
• The driving pattern selector sw it
ch is set to “SNOW” mode.
• The wipers are operated at high speed (radar), or either high or low speeds (l
aser). This includes high and low speed operation with the wiper lever in the
AUTO position.
• The vehicle’s speed falls below 25 mph (40 km/h). In this case, you must apply th
e brakes manually to slow the vehicle.
If the preset speed automatically cancels out for other than the above reasons, the
sy
stem may have malfunctioned. Do not operate the dynamic radar/laser cruise
control. You may continue driving, howe ver have your vehicle checked by your
Lexus dealer at the earliest opportunity.

■Vehicle-to-vehicle distances
Select a vehicle-to-vehicle distance appropriate
to traffic conditions. The approxi-
mate vehicle-to-vehicle distance based on time interval when driving at 55 mph
(88 km/h) is sho
wn below:
If the vehicle speed is slower than 55 mph (88 km/h), the distance will be shorter
than ab
ove.
■Millimeter wave radar lase r sensor/ Laser radar sensor
The radar or laser sensor automatically detects dirt on the sensor or grill cover
(r
adar cruise control), or the sensor glass (laser cruise control). If dirt is detected, a
message is displayed on the multi-informatio n display, and the radar or laser cruise
control function is automatically cancelled.

When driving
CAUTION
■To avoid accidentally engaging the cruise control
Keep the ON-OFF switch OFF when not in use.
■To avoid death or serious injury
The following conditions are unsuitable for cruise control use:
• In bad weather (rain, fog, sno
w, sandstorms, etc.)
• If the wipers are operated at high speed (radar cruise control), or at high or low spe
eds (laser cruise control.) This includes when the wiper lever is set to the
“AUTO” position.
• In heavy traffic.
• On roads with sharp bends.
• On slippery road surfaces.
• On steep downhill slopes.
• When the warning tone sounds frequently.
• On roads with steep, short inclines and declines.
• When exiting from, or when ente ri
ng or merging onto a freeway.
■When using the dynamic radar/laser cruise control
Always drive carefully and attentively.
Do not rely on the system to avoid accidents or control the vehicle’s speed in emer -
gency situations. The cruise control is not a collision-av
oidance system.
■Conditions which hinder the radar cruise control's vehicle detection capability
●The rear section of the vehicle ahead is extremely small (unloaded trailer etc.)
●The vehicle ahead or other vehicles are flinging up water or snow.
●Heavy luggage in your trunk or on your rear seats causes the nose of your vehicle
to rise.

2-4. Using other driving systems
CAUTION
■Conditions which hinder the laser cruise control’s vehicle detection capability
A delay in detection of a vehicle may occur in the following situations. You must
ap
ply the brakes manually to avoid accidents.
• The vehicle ahead has higher ground clearance, meaning the reflectors are in a higher position
.
• The rear section of the vehicle ahead is extremely dirty.
• Surrounding vehicles are fl in
ging up water or snow.
• Your front view is obscured by excessive exhaust smoke.
• Protective film is attached to the reflectors of the vehicle ahead, or they are d
amaged.
• Reflectors are not installed on the vehicle ahead.
• Heavy luggage in your trunk or on your r
ear seats causes the nose of your vehi-
cle to rise.
• A vehicle cuts in at short range.
• A motorcycle is traveling along the side of the same lane
■To ensure the radar/laser cruise control system functions correctly
●Keep the radar sensor and grille cover/la ser sensor glass clean. When cleaning,
use a soft cloth and be careful not to damage the sensor or grille cover.
●Avoid strong impacts around the sensor, as incorrect sensor alignment will result
in system malfunction. A special device is required to adjust the sensor alignment.
See your Lexus dealer for adjustment.
●Do not disassemble the sensor.
●Do not affix stickers (including transparent stickers), or attach accessories
around the sensor or grille cover/sensor glass.
●Do not modify or paint the grille cover. When replacing the cover, be sure to use
a genuine Lexus cover. *
